Problems solved by technology

[0003] Traditional H-shaped honeycomb steel beams usually use flat webs, which have the following disadvantages to be overcome: the out-of-plane rigidity of flat webs is weak, and the shear buckling capacity is low, which limits the expansion ratio of honeycomb steel beams and reduces the structural performance of honeycomb steel beams. Restricted; considering the requirements for member stiffness during manufacture, transportation and installation, the height-to-thickness ratio of the flat web cannot be too large
However, the above measures will not only increase the amount of steel used and the manufacturing process, but also affect the aesthetics of the honeycomb steel beam

Embodiment 1

[0044] Example 1: as Figure 1 to Figure 3 As shown in the figure, the corrugated web H-type honeycomb steel beam in this embodiment is a rectangular hole type corrugated web H-type honeycomb steel beam, which is composed of a corrugated web and upper and lower flange plates, wherein the corrugated web is welded on the Between the upper and lower flange plates, a plurality of rectangular openings are arranged on the corrugated web, the holes of the plurality of rectangular openings are the same and are arranged at equal intervals, and the cross section of the corrugated web is regular corrugated.

[0045] like figure 1 As shown in the figure, the processing of the H-shaped honeycomb steel beam with the rectangular hole type corrugated web includes the following steps:

[0046] 1) The flat plate is continuously molded to form a corrugated web by molding equipment;

[0047] 2) Cut the corrugated web along the set cutting path, so that the corrugated web is divided into several...

Embodiment 2

[0063] Embodiment 2: as Figures 6 to 8 As shown, the difference between this embodiment and the first embodiment is that the shape of the openings on the corrugated web is hexagonal. At this time, by calculating and planning the forming and dividing paths, each dividing unit forms a half of a hexagon, and then welding is carried out with reference to the corresponding welding method of the first embodiment, that is, the first cutting unit 1 and the second cutting unit 4 are welded, The second cutting unit 2 and the third cutting unit 3 are welded.

Embodiment 3

[0064] Example three: as Figure 9 to Figure 11 As shown, the difference between this embodiment and the second embodiment is that the sizes of the hexagonal openings on the corrugated web are different, and the difference is also realized by calculating and planning the forming and dividing paths. .

Abstract

The invention relates to the technical field of structural engineering, in particular to a corrugated web H-shaped honeycomb steel beam and a manufacturing method thereof.The corrugated web H-shaped honeycomb steel beam is composed of a corrugated web, an upper flange plate and a lower flange plate, the corrugated web is welded between the upper flange plate and the lower flange plate, a plurality of open holes are formed in the corrugated web, and the upper flange plate is welded to the lower flange plate. The multiple open holes are the same in hole pattern and arranged at equal intervals, and the cross section of the corrugated web is in a regular corrugated shape. The corrugated web pore-forming processing technology has the advantages that the honeycomb steel beam can be manufactured on the basis of ensuring that materials are not wasted any more, and the corrugated web pore-forming processing technology is a novel efficient and energy-saving corrugated web honeycomb steel beam machining and manufacturing technology; the steel pipe pile is convenient to process, material-saving, good in stress performance, high in bearing capacity and good in engineering value.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a corrugated web H-shaped honeycomb steel beam and a manufacturing method thereof. Background technique [0002] In the past, a new type of steel beam with a series of equidistant and the same hole shape was formed by cutting along the path designed on the web of the H-shaped steel beam by rolling or welding, and then dislocation welding. The web steel beam has higher flexural rigidity and flexural bearing capacity, and the holes formed at the same time can pass through the equipment pipeline, saving the building space. [0003] Traditional H-shaped honeycomb steel beams usually use flat webs, which have the following shortcomings to be overcome: weak out-of-plane stiffness of flat webs, low shear buckling bearing capacity, which limits the expansion ratio of honeycomb steel beams, and makes the structural performance of honeycomb steel beams difficult. Restricted...
